Laminar flow can be defined by the help of Reynold's number that can be determined by conducting experiments. A Reynold number <=2000 indicates that the flow is laminar.

What are flow patterns around a stationary object in laminar flow?

This question is its own answer. The flow patterns in laminar flow are laminar.


What are examples of laminar and turbulent flow?

The Reynolds number, Re = VD/&upsilon;, can be used to measure the laminarity of flow. The smaller the Reynolds number, the more laminar the flow. Therefore, to achieve better laminar flow, V and D (velocity of fluid and diameter of pipe) should be small and &upsilon;, the kinematic viscosity of the fluid, should be large. Therefore, since pipe diameter and viscosity is fixed in this circumstance, the slower the velocity of the flow, the more laminar the flow. Open the faucet to a small degree and the flow will be laminar. Turn the facet open fully will (for some faucets) cause turbulent flow depending on the maximum velocity of water allowed by the faucet.


Is Bernoulli equation applicable for unsteady flow?

The equation assumes steady state or laminar flow and hence cannot be used for turbulent flows.


Why poiseuille equation not applied to turbulent flow?

Coz poiseuille eq is for poiseuille flow, which is a laminar flow, not turbulent flow. And it also need to be a fully developed , pressure driven flow.


Why laminr flow is required?

well laminar flow is required in aircraft and race cars .it is required sine we know that air transfers its momentum by sticking to the surface of the body . and thus creates pressure . now if the flow is turbulent it is not going to stick to the surface and going to destroy a considerable amount of momentum and not create sufficient amount of pressure that's why we need to have laminar flow in aircrafts and race cars. it is desired to be there in pipes in order to have a smooth flow.

Why is no obstruction important for air flow techniques?

The laminar flow hood depends on the laminar air flow to sweep away pathogens from the hood. If there is obstruction, the laminar air flow pattern will be disrupted. The laminar air flow will then change to turbulent air flow.

What is the effect that radius changes have on the laminar flow of a fluid?

Laminar flow is the free-flowing blood in the middle of the vessel. Therefore, larger the radius of vessel, more the laminar flow. Smaller the radius of vessel, lesss the laminar flow. Laminar flow is directly reltated to the radius of a vessel.

Where can someone purchase a Laminar flow hood?

Laminar flow hoods can be found through ebay's website. Companies NuAire, Terra Universal, and Air Clean Systems all offer their own laminar flow hoods (also called laminar flow closets and tissue culture hoods) on their official websites.


What are the differences between horizontal and vertical laminar flow hoods?

In a horizontal laminar flow hood, the laminar air flows towards the outside (i.e. towards the worker). There is hence no protection to the worker and it is not suitable for cytotoxic drug preparation. In a vertical laminar flow hood, the laminar air flows downwards from the top, providing more protection for the workers. Vertical laminar flow hoods are hence suitable for preparing cytotoxic drugs.
